Abstract: A method includes, in a computing system in which one or more workloads access memory pages in a memory, defining multiple memory-page lists, and specifying for each memory-page list a respective different scanning period. Access frequencies, with which the memory pages are accessed, are estimated continually by periodically checking the memory pages on each memory-page list in accordance with the scanning period specified for that memory-page list, and re-assigning the memory pages to the memory-page lists based on the estimated access frequencies. One or more of the memory pages are evicted from the memory based on a history of assignments of the memory pages to the memory-page lists.
